From NBC/NJ's Mike Memoli... But we in the Hillary Clinton traveling press corps were just alerted that the sign-up page for transportation and hotel rooms was updated for the coming week. Interestingly, it allows us to sign up for travel after June 3, the final primary day -- right up through June 6.

A sign of optimism? A sign she's not giving up anytime soon? "Sign up and see," was all Clinton spokesman Jay Carson said.

Carson later added, "There are a lot of places to go between now and November 4."
